not true.
one side is an altcoin the other is bitcoin.
period.
I think you misunderstood what he wrote. The other admins have their own sidechant, the lightning network. And that network would have an advantage when bitcoin would turn out to be expensive and slow or not unreliable. Because transactions would swith there. Which, by the way, is their argument. We need to take out transactions from bitcoin and leave bitcoin as a high value transaction system.
Surely not what most bitcoiners would want. Or the vision satoshi had with bitcoins.
So yes, both sides have their own altcoin in mind.
Meh, as long as bitcoin does not get highjacked. They can build whatever they want on top of it.
But high value transaction system? Sign me up already.
Though the problem starts when they promote 1 MB blocks which will effectively make bitcoin worse for users. Higher fees, unreliability about transactions going through and so on.
You should not create a sidechain, claim that transactions should move from bitcoin to sidechains and to make that possible make bitcoins less useful.
That simply is not ok.
And what about hijacked? Practically no one using xt is a fan of hearn. It is only a vote for bigger blocks. No one wants the other stupid things he wants.
